Sonos Amp buzzing

My Sonos Amp has a buzzing/humming sound coming from inside the unit. It is very audible even when no music is playing and speakers are disconnected. My local shop and the Sonos support have been unable to resolve the issue.

Because it is out of warranty, Sonos will only offer a 30% discount on a new one. I am very hesitant to buy another when this issue could happen again (it seems to be a known issue when searching communities).

Very disappointing response from Sonos. This is a high end piece of kit and should be backed up by Sonos. Anyone had this issue or had a better resolution?

The 30% discount is the standard Sonos response to hardware issues as they don’t do repairs. Unlikely you will get a better resolution from them imo. 
 

My amp is long out of warranty as well. I really like it but can’t see me buying such an expensive device, even with discount, as the hardware platform is 6 years old and overdue for a refresh when there is a competitor for 1/3 the price that has more features and better software but ymmv.

There are some EU companies that offer SONOS repair.

Interesting… ​@buzz is answering a question about buzzing.

Yes, it’s a giggle. I am overly sensitive to and hate miscellaneous noises. That’s why I use the handle. I’m rarely invited back to audiophile ‘my dog is better than your dog’ type showdowns because I notice and comment that all of the dogs have fleas.

I’m the same way.  Never learned to swallow my opinions.

So I seem to have 4 options. The buzz is too loud and audible when not in use so:

  1. Turn the Amp off at the wall whenever not in use, which defeats the purpose and means it has to boot up each time I want to listen to music (while it still buzzes);
  2. Accept the 30% discount and fork out $800 NZD to replace it;
  3. Buy another brand like Wiim which would cost much less than the discounted sonos;
  4. Go back to my old Yamaha analog amp with bluetooth adaptor (at no cost);

What would you do!?

Have you looked at the used market? Might find something for less but you’d not have a warranty.

Can you physically move the AMP to a location where the buzz is not so annoying?

Buy some Ace headphones, the noise cancelling is very good, you wont hear the buzz from the Amp, whilst wearing the headphones.

On a serious note, is the Amp on a hard surface / AV unit? Could the buzzing be supressed by placing on a rubber/foam type mat?
